| description | The knowledge of the geometry and the physical properties characterizing the subsurface has been
a challenge for groundwater exploitation. The relationship between lithological properties,
electrical distribution and wave velocity was explored for this research as a means of detecting
porous aquifers. The geophysical exploration involved electrical resistivity and seismic refraction
surveys in parts of Selangor and Pahang areas of Malaysia. 2D resistivity conducted in these areas
generated profiles from which probable positions of groundwater were identified. The field acquired
resistivity data were processed with the use of RES2DINV software. For the seismic refraction
method, magnitudes of wave velocity values were used to estimate depths to aquifer zones and
to map the bedrock surface and subsurface structures. The high resolution seismic data that was
gathered was processed and interpreted with the GREMIX program. A good hydrogeological interpretation
was possible by constraining the geoelectric inversion and seismic velocities using
information from known geology of the study areas. Both methods were effectively combined to
ascertain the presence of fracture aquifer in hardrock complexes. Good correlation between
electrical resistivity and seismic survey results confirmed the usage of integrated geophysical
techniques as a reliable tool in providing useful information of the subsurface. |
